TO ALL WHOM IT MAY CONGERN:

Be it known that I, LEFFERT R. CORNELL, of Flatbush, Kings county, New York, have invented a new and improved Superheaterg and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this speciiication.

The present invention consists in anovel construction and arrangement of pipes and tubes for the conduction and passage of steam for the superheating of the same, the principle of which construction consists in providing barriers to the passage of the steam, and in so runningthe pipes or tubes that the steam willlbe made at points of its passage through the superheater to strike against the sides or surfaces thereof, and thus have its particles so broken or separated a's to bethe more fully and perfectly subjected to the action of the heated currents circulating about or surrounding the super-heater. In the accompanying plate of drawings my improvement in superheaters is illustrated- Figure 1 being a plan or top view of the same.

. A A, in the drawings, represent two similar cylinders or drums, placed one alongside of the other, but at a short distance apart, and parallel to eachother, and with cach cylinder supported in a horizontal position, or nearly so, by means of uprights, A2, at suitable points. In these cylinders, at different points of their length, and at equal distances apart, or nearly so, is a series of cross-heads or partitions, B, dividing the cylinders into a series of chambers or spaces, B2. C, a series of pipes or tubes, copnecting the two cylinders A together. These pipes C extend upward from the cylinders, in an arched or curved shape, opening at each end in the upper side thereof, and are so arranged as to form a continuous communication between the several chambers ofthe cylinders, from one end to the other. E, pipes, running along the under side of the cylinders, from one end to the other, with the several chambers of which cylinders the pipes E communicate through short connecting pipes D. At one end of one of the cylinders A the steam is admitted, which, passing into the same, strikes against its first partition, and escapes up through the first arched pipe Cinto the first chamber of the next cylinder, against the side of which it strikes, owing to the downward direction of the tube, and from thence passes through the next pipe O, striking in-its passage thereto against the first partition of the said second cylinder into the second chamber of the first cylinder, against the sides of which it impinges, and so on; through the third pipe to the second cylinder, and from thence back again to the irst cylinder, and so on, until it reaches the end of the cylinders, when it there escapes through any suitable outlet provided for it; th'e steam as it is passing through the cylinders, as above described, being subjected to the action of heat, which causes it to become superheated to a greater or less extent, and according to the degree of heat employed, as is obvious. But, by the peculiar manner in which the steam passes through the superheater, it is, as it were, broken up or separated, and consequently the more perfectly subjected to the action of the heat employed to superhcat it, economizing not only in the heat necessary in a corresponding degree, but at the same time enabling the steam to be so supcrheated as to be, as it were, perfectly dry. Through the pipes E the condensed steam or water, if any, escaping from the cylinders can he drawn ed when so desired.

Having `thusdescribed my invention, Awhat Iclaim as new, and desire tosecure by'Letters-Patent, is

The supcrheater, constructed as described,vconsisting of the parallel cylinders A divided into chambers I32 by heads B, and supported by. means of the uprights A2, said chambers connected alternately by means of the curved pipes C, and connecting withl the parallel condensing pipes E beneath each cylinder by means of the short pipes D, as herein shown and set forth for the purpose specified.

The above specification of my invention signed by me this day ofvApril, 1867.

LEFFERT R. CORNELL.
